Hi,
Ok Do you have the VISTA DISC?
To start this Windows install insert the first CD or the DVD into the drive and start or restart your computer
"Press any key to boot from CD or DVD", hit any key on the keyboard to continueThe Windows Vista install will the begin to loadSome of these stages can take quite sometime so be patient.Now select your install Language, Time and Currency Format, keyboard type, once you are happy with the settings, Click on "NEXT" to continueFrom the next screen click on "Repair Your Computer" to continue.Windows will now search for Windows Installations.From the next screen select the operating system on which you wish to do a repair. Select it, then press "NEXT" to continueYou are now at the "Recovery Options" menuFrom the "Recovery Options" menu select "STARTUP REPAIR"...
Windows will search for problems (This may take sometime so be patient)....If problems are found then Windows will attempt to repair themOnce completed Windows will prompt you to click "FINISH" to complete the repair.Repair details will now appear, read if need be and then click "CLOSE"The computer will now reboot, and if Windows was successful in its repair then it should boot to the desktop or login screen.
You can get the files from the the Xp also Start Xp Open "My Computer" then open the Drive in which you have VISTA installed and copy your essential files to another drive

Ok In the disk management window right click on the drive H and make it active
I think there is another problem may be some files are corruted if possible please can you let me know the eaxct error that you get when trying to start VISTA.
In the above post I have mentioned the procedure for repair please run it again and select System Restore from the recovery option instead of Startup Repair.
Because this is not a active or inactive problem the file is corrupted that can only be restored by repair or restoreing.
Then there is no way other than repairing or reinstalling VISTA for further reference you can goto the link below and if I know that where is your files situated exactly in the Vista is it Desktop or Documents etc. I will try to help you for recovering the files
